Yes, it's a RCA Mini-Speaker Pro-X33AV. Because it's discontinued and
was a stand-alone, I got it and the phone plug for less than 20 bucks.
I already had plenty of speaker wire at home. Last night I turned up 18
reviews of this speaker on eham.net and it gets a 4.8 out of 5.0
rating. That's not bad. It is a good speaker for shortwave listening.
No doubt about it.
